Field of the Invention This invention relates to apparatus for receiving coke pushed from a horizontal coke oven and more particu- .larly to a rotary drum receiver positioned perpendicuoven battery and has spraying devices thereon to quench the coke.

Co-pending application, Ser. No. 187,404, entitled Material Transfer Apparatus For A Rotary Drum, filed Oct. 7, I971, discloses dust collecting apparatus positioned adjacent the discharge end of the drum. In both U.S. Pat. No. 3,367,844 and the above co-pending application-the coke is discharged from the drum onto an endless conveyor. The drum type receivers have in the past been employed as quenching devices and there is a need for a drum type receiver that is arranged to receive the coke from the coke oven chamber and to displace at least a portion of the coke from the lower quadrant of the drum receiver chamber while additional coke is introduced into the drum receiver chamber. Further, there is a need for a drum type hot coke receiver that receives coke from a coke oven chamber without discharging dust into the atmosphere.

SUMMARY OF THE INVENTION The present invention is directed primarily to improvements in receivers for hot coke that is being pushed from a horizontal coke oven' chamber and includes a drum type receiver mounted on a movable support member. The drum type receiver is arranged to be pushed adjacent the coke discharge end of the coke oven chambers with the axis of the drum extending substantially horizontally and perpendicular to the coke oven battery. The drum receiver has a chamber rotatable about the drum axis with a central opening for introducing coke into the drum receiver chamber from the coke oven and an outlet opening to discharge the coke from the drum receiver chamber. A coke oven guide connects the outlet opening of the coke oven chamber with the central inlet opening of the drum receiver and the coke discharged through the coke oven guide is deposited in the lower quadrant of the drum receiver chamber. During the pushing operation the drum receiver is rotated about its axis to displace at least a portion of the coke in the lower quadrant of the drum receiver chamber to provide space for additional coke discharged from the coke oven.

A housing encloses the drum receiver and has an open upper end portion. Filter members close the housing open end portion and suitable suction means are provided to collect the dust formed in the receiver chamber in the filtermeans. The drum receiver has a plurality of annular ring members which are supported on roller members which, in turn, are supported on the movable support membenCertain of the rollers are driven to rotate the drum receiver and displace the coke within the lower guadrant of the drum receiver chamber. Other rollers are provided to abut the side walls of one of the ring members to maintain the drum receiver on the support member and permit longitudinal expansion and contraction of the drum member.

The housing enclosing the drum receiver has a side opening with, parallel rail members supported thereby. The coke guide is supported on the rail members and is movable into the central opening of the drum receiver when not in'use.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view of the coke receiving apparatus in elevation and partially in section.

FIG. 2 is a view of the coke receiving apparatus taken parallel to the longitudinal axis of the coke oven battery, illustrating a coke guide device between the outlet opening of a coke oven chamber and the inlet opening of the coke receiving apparatus.

FIG. 3 is a top plan view of the coke receiving apparatus, illustrating the dust filters and suction fans.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings and particularly to FIG. 2 there is illustrated a coke oven battery generally designated by the numeral 10 that includes a plurality of transversely extending coke oven chambers 12. The coke oven battery has a coke discharge side 14 in which the coke oven chambers 12 have coke discharge openings 16. The coke formed in the coke oven chambers 12 is discharged through the discharge opening 16 into coke receiving apparatus which is generally designated by the numeral 18. Between the coke receiving apparatus 18 and the coke oven battery discharge side 14 is a conventional coke guide 20 that is supported on a coke guide car 22. The coke guide 20 is arranged to conduct the coke discharged from the coke oven chamber 12 to the coke receiving apparatus 18.

Referring to FIGS. 1 and 2 the coke receiving apparatus 18 includes a rotary drum receiver 24 that has an axis 26 illustrated by the line in FIG. 2. The drum receiver 24 has a generally annular configuration with a pair of spaced annular side plates 28 and polygonal end plates 30 that provide a generally U-shaped cross section for the drum receiver 24. The annular side plates 28 have a central opening 32 through which the coke is discharged from the coke guide 20 into the chamber of the drum receiver 24.

The drum receiver 24 is mounted on a movable support member 34 that is, in turn, mounted on wheels 36. Rails 38 extend parallel to and along thecoke dis charge side 14 of coke oven battery 10 and the movable support member 34 is arranged to move on the rails 38 to position the coke receiving apparatus 18 opposite a selected coke oven chamber 12. Pairs of rollers 40 are mounted on supports 42 which extend upwardly from the support member 34. v

The drum receiver 24 has a pair of ring like tires or bearing surfaces 44 secured to the outer wall 30 and are supported on the rollers 40. In this manner the drum receiver 24 is rotatably supported on rollers 40. Suitable drive means such as a diesel engine or the like (not shown) are connected to certain of the rollers 40 and arranged to rotate the rollers 40 which, in turn, rotate the drum receiver 24 about the axis 26. As illustrated in FIG. 2, a pair of rollers 46 are suitably mounted with their axes 48 substantially vertical and the lower surfaces abut the side walls of the bearing member 44. With this arrangement, the rollers 46 maintain the rotatable drum receiver on the movable support member 34 and permit expansion and contraction of the metallic drum receiver 24.

Housing 50 forms an enclosure around the drum member receiver 24 and has an open top portion 52. A

suitable filter, such as a gravel or fiber filter, 54 (FIG.

tary receiving drum 24 iscollected .on the filter and not discharged to the atmosphere.

The housing 50 has a central opening 58 witha suitable enclosure or cover thereon and a pair of rails '60 are secured to the housing 50 and extend into the opening 32 of the drum receiver 24. The coke oven guide has rollers 62 which are positioned on the rails 60. With this arrangement, the coke guide 20 .can be moved away from the coke oven chamber 12 within the rotary receiver drum 24 so that the coke guide 20 can be transported with the coke receiving apparatus 18 as it is moved from one coke oven chamber to another. When the coke guide 20 is moved into operative position abutting the opening 16 of a coke oven chamber it is preferred that the coke guide 20 be supported by I coke guide car 22 on roller 64.

Pocket type lifter devices 66 are secured to the inner surface of the drum receiver wall and are arranged upon rotation of the drum to displace coke within the lower quadrant of the drum receiver "chamber and move the cokeupwardly therein. A chute 68 has a top opening 70 that opens into the chamber of the drum 24 and has a movable lid 72. When the lid is in the open position as indicated in solid lines in FIG. 1 rotation of the drum 24 will convey coke particles by means of the pocket lifters 66 to the upper quadrant of the chamber and discharge the coke onto a plate 25 and the coke will then slide the plate 25 through the opening 70 into chute 68. When the gate 72 is closed the coke will not pass through the opening 70.

The housing 50 has a hopper like bottom portion 74 t which is arranged to receive the coke that occasionally spills over from the drum 24 and a suitable collecting rotary drum receiver 24. The coke flows by gravity in the lower quadrant of .the drum receiver chamber 24 and the drum 24 is rotated at a preselected peripheral speed by the driven rollers 40. Therotation of the drum 24 displaces at least a portion of the coke in the lower quadrant of the drum receiver chamber to provide room for coke subsequently pushed from the same chamber. During the pushing operation the suction means (not shown) may be employed to periodically 7 remove the coke within hopper portion 74.

A coke quenching spray 76'is connected by means of a conduit 78 to a source of water 80 to provide a water quenching spray within the lower quadrant of the ,drum

receiver 24.

The above described apparatus is arranged to receive hot coke discharged from the coke oven chamber 12 in the following manner. The coke guide 20 is retracted through the opening 58 in housing within the opening 52 of the .drum receiver 24. The movable support and encloses the opening 16 in the coke oven chamber 12. The coke is then pushed from the coke oven chamber 12 through the guide 20'into the opening 32 of the fans 56 and the quenching spray 76 are energized. The water spray 76 quenches the coke and the suction fans 56 withdraw the vapors and dust through the filter 54 where the dust particles are collected and not discharged to the atmosphere. When it is desired to discharge the coke from the receiver Home a coke wharf 82 the lid is'opened and the drum receiver 24 is rotated. The coke in the lower portion of the-drum re ceiver 24 is picked up by the pocket devices 66 and deposited either on the inclined plate 25 or directly in the opening of chute 68. The coke thus deposited on the inclined plate and the coke entering opening 70 is discharged through'the outlet opening 84 of chute 68 onto the coke wharf 82.
